Google Wave

Hello.
So I've got an invitation to Google Wave from my friend yesterday. Or maybe a day before yesterday, it doesn't matter. Well, it's pretty cool, I can say. Especially when you don't have to look at '-- is typing, -- is typing, -- is typing'... and so until your friend hits enter. But that's just something you can do with it. I haven't got many contacts on it (only my friend who invited me) yet. I wonder when will they launch open beta... I will definitely invite all my friends to join it. Well, it's not an IM, I can not call others (can I? I think I can't) and turn on my webcam, but anyway. It's a nice alternative to social websites and for some people even IM.

I got some invitation like months ago. I've joined it and checked it once, I didn't get to check it in a while. I don't know but I don't have many contacts in it so I can't used it more often that I thought.
